I find the factory Marlin-stamped mag for teh Camp carbine 45 works well (it should). However, I tried some pachmayrs and Mec Gars in the magwell, and they would not even fit! Strange for a 45ACP-based rifle. In fact, I am uncertain whether it is the mag body width or the follower, or size of mag catch slot. Does anyone have suggestions for reasonably inexpensive sources of Mags for the camp Carbine 45?
